Summary

Low levels of vesicular-arbuscular mycorrhiza formation were found in a normally nonmycorrhizal species,Chenopodium quinona, when sprayed with sublethal doses of simazine. Application of simazine also increased exudation of sugars and amino acids from roots. It is suggested that this increase in root exudation is responsible for the unusual formation of mycorrhizae in this species.
